A 45 minute talk about designing a single button

Ollie Campbell gave a 45-minute talk about designing a single button for quantity selection on an online grocery shopping website. The talk discussed the user research that showed people wanted a faster shopping experience and the challenges of building a button that could update prices based on quantity while maintaining accessibility standards. User testing found the redesigned button improved shopping speed by 24% and increased user satisfaction scores, though some users still found it difficult to use.
